INTRODUCTION

GETTING STARTED

WHAT’S IN THE BOX

Packed with your M4 you will nd

· An AM loop antenna.

· A FM ribbon-wire antenna with balun.

· A DAB antenna (230V version only)

· A removable AC cable (if you wish, any IEC-standard AC cable of suitable

wattage may be substituted).

· The M4 remote control with 2 (two) AA batteries.

· This owner’s manual.

SAVE THE PACKAGING

Please save the box and all of the packaging in which your M4 arrived.

Should you move or otherwise need to transport your M4, this is by far the

safest container in which to do so. We’ve seen too many otherwise perfect

components damaged in transit for lack of a proper shipping carton, so

please: Save that box!

CHOOSING A LOCATION

Choose a location that is well ventilated (with at least several inches to both

sides and behind), and that will provide a clear line of sight, within 23feet/7

meters, between the M4’s front panel and your primary listening/viewing

position—this will ensure reliable infrared remote control communications.

The M4 generates a modest amount of heat, but nothing that should

trouble adjacent components. It is especially important that sucient

ventilation be provided. If you are contemplating on locating the M4 within

a cabinet or other furniture, consult your NAD audio/video specialist for

advice on providing adequate airow.

ABOUT M4

The M4 Tuner is equipped with DAB (230V version only), XM-input (for

120V version only) and RDS (Radio Data System), bringing a wide range of

information to radio listeners. These are in addition to the normal AM/FM

band reception.

Now in use in many countries, RDS is a system for transmitting station

identication, a description of the station’s program type, indication of

national, regional or local programs and the correct time. RDS also allows

you to search for favorite program types.

The M4 is “XM Ready” which means that with the addition of separately sold

XM Mini-Tuner CPC-9000 and XM Mini-Tuner Home Dock, it has everything

you need to listen to live XM.

Until now, analogue radio signals such as FM or AM have been subject to

numerous kinds of interference on their way from the transmitter to your

radio. These problems were caused by mountains, high-rise buildings

and weather conditions. With DAB (Digital Audio Broadcast), you can now

receive CD-like quality radio programs without any annoying interference

and signal distortion.

ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ

The M4’s internal AM/FM tuner oers very high quality sound from radio

broadcasts. The reception and sound quality will always be dependent to a

degree however on the type of antenna(s) used as well as proximity to the

broadcast origin, geography and weather conditions.

ABOUT ANTENNAS

The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-

antenna input using the included “balun” adapter and should be fully extended

to form a “T”. This folded-dipole antenna will usually work best when oriented

vertically, with the arms of its “T” fully outstretched and arranged perpendicular

to the origin of the desired broadcast. There are no “rules” however, and

experimenting freely with antenna placement and orientation may yield the

clearest sound and lowest background noise.

In areas of poor FM reception, an exterior FM antenna can improve

performance dramatically. If radio listening is important to you, consider

consulting an antenna installation professional to optimize your system.

The supplied AM “loop” antenna will usually provide adequate reception.

However, an exterior AM antenna can be used to improve reception.

Consult an antenna professional for more information.

ABOUT RDS

The Radio Data System (RDS) permits sending small amounts of digital

information using conventional FM radio broadcasts. The M4 supports

two RDS modes, station-name (PS mode) and radio-text (RT mode). Not

every FM station incorporates RDS in its broadcast signal. In most areas you

will nd from one to several RDS-enabled stations, but it is by no means

impossible that your favorite stations will not be broadcasting RDS data.

VIEW RDS TEXT

When an RDS-enabled FM broadcast is tuned, after a brief delay the lower

line of the VFD will show its station-name (PS) text: “ROCK101,”for example.

Toggle the front-panel [INFO] key to scroll among other MODE settings for

the station’s radio-text (RT) readout, if any, which might scroll song or artist

name or any other text of the station’s choosing.

ABOUT DAB RADIO (230V VERSION ONLY)

Until now, analogue radio signals such as FM or AM have been subject to

numerous kinds of interference on their way from the transmitter to your

radio. These problems were caused by mountains, high-rise buildings

and weather conditions. With Digital Audio Broadcast (DAB), you can now

receive CD-like quality radio programs without any annoying interference

and signal distortion. DAB broadcasts use digital signals rather than

traditional analogue transmissions, thus providing clear high quality

reception. You get far more robust reception and virtually hiss or crackle

free sound with DAB as long as you are within a good coverage area.

With DAB, the listener can scroll through a list of available stations - then

instantly tune to the station of his choice. There is no need either to

remember channel frequencies. All broadcasts are selected by simply

selecting the service name.

The M4 makes it possible for you to enjoy listening to DAB broadcasts.

Connect the other end of the supplied DAB antenna into the DAB antenna

terminal and start enjoying the CD-like quality sound and expansive

content selection available with DAB.

DAB ANTENNA ASSEMBLY

1 Connect the antenna to its base.

2 Plug-in the antenna connector to the M4 DAB antenna terminal.

DAB OPERATION

With the supplied DAB antenna already connected to the M4, you can

now carry out the M4 to receive DAB broadcasts. Use either the front panel

buttons or remote control keys for the following procedures.

1 Toggle [BAND] button until DAB mode. The VFD will show “No Service

List” indicating that there are no scanned DAB broadcast services yet.

This is the default mode of the DAB mode.

2 To tune to DAB broadcast services, press [MODE] and then toggle the

front panel’s [TUNE ] to select either “Full Scan” or “Local Scan.”

Press [ENTER].

FULL SCAN will enable the scanning of the full range of digital

frequencies (Band III and L-Band).

LOCAL SCAN performs local scanning of available DAB services in your

area. Check with your dealer or visit www.WorldDAB.org to check the

applicable digital transmission frequencies in your area.

3 Upon selecting either “Full Scan” or “Local Scan,” automatic scanning

will be performed. This sequence cannot be interrupted. During the

sequence, the following message will be visible in the VFD.

The bars show the progress of the sequence. When scanning is

completed, the last number shown on the right side of the VFD

corresponds to the total number of DAB broadcast stations found.

Then, the rst station is tuned in (See “Alphanumeric” section below to

understand the order or arrangement of stations).

4 The strength of the incoming signal can be shown on the VFD by

pressing the [ENTER] button. The more segments visible in the lower

display line, the stronger the signal. By changing the position of the

antenna, you can increase the signal strength. You can also opt for an

external antenna. Consult an antenna professional for more information.

“Ensemble” is selected as the mode of station order, the radio stations are

arranged in the order of their ensemble names.

NOTE

 Ensembleisalsointerchangeablytermedas“multiplex”byother

broadcastproviders.

ACTIVE

Active stations are listed at the top of the channel list. Those channels

that are in list but have no service in the area will be displayed last in the

channel list.

DRC VALUE

The level of compression of stations can be set to eliminate the dierences

in dynamic range or sound level between radio stations. Popular music

would normally be more compressed than classical music, resulting in

possible dierent audio levels when changing from one station to the

other. Setting the DRC to “0” means no compression, “1/2” indicates medium

compression and “1” shows maximum compression. No compression is

recommended, especially for classical music.

1 While listening to a DAB broadcast, press front panel’s [MODE] button

and then [TUNE ] to select “DRC.” Press [ENTER].

2 Toggle [TUNE ] to select through “DRC 0,” “DRC 1/2” and “DRC 1.”
